Checked online there is literally no news regarding the same. But do you know that they are operating without any licence since 2016? They might not really be considered legal now. But at the same time customer review ratings have always been high for them so they continue to flourish in the US since 2011. ( Some information I got from google)
If they are not supporting bitcoins as a method of payment in betting hands down. This is something that might come just from the new rules and regulations from the commission therefore you can't really do anything about it.
Try some other casinos.
It might be due to high fee as well, are they still using ETH tho?? It was also listed in the top bet online sports book as well.
They might change their decision in a while tho, wait for any news or statements.
